Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607234, here are decompositions:

7 + 31607227 = 31607234
97 + 31607137 = 31607234
271 + 31606963 = 31607234
277 + 31606957 = 31607234
283 + 31606951 = 31607234
331 + 31606903 = 31607234
523 + 31606711 = 31607234
577 + 31606657 = 31607234

Showing the first eight; more decompositions exist.
